Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Storage Of Multiple, Indexed Backup Sets On The Same Media

Abstract

A storage-management application may create a backup set, which contains a copy of all active backup objects for a single client node. Disclosed is a mechanism whereby multiple backup sets can be stored on the same media volume or set of volumes.

Storage Of Multiple, Indexed Backup Sets On The Same Media

Background

A storage-management application may store and track files as individual objects. It
may also create a "backup set", which contains a copy of all active backup objects for a
single client node at a specific point in time, stored sequentially on media such as tape.
Backup sets fill a number of different storage management needs. For example, they
are frequently used as:
long term archival copies of critical business data,
off-site copies of backup data used for disaster recovery,
portable backup copies that can be restored directly on the local computer, without
the need for a remote storage management server.

Description of the Invention

This invention provides a mechanism whereby multiple backup sets can be stored on
the same media volume or set of volumes. Key elements of the invention are as follows.

During a backup set generation operation, multiple individual backup sets can be
generated within a "multi-set"

The individual backup sets are stored sequentially within the multi-set, with no
intermingling of data from the different backup sets
Each multi-set is stored on one or more media volumes
The multi-set contains a Table of Contents (TOC) for each individual backup set
Individual TOCs are grouped near the end of the multi-set
A master table of contents (MTOC) is stored at the end of the multi-set after the
individual TOCs

The illustration below provides a high level view of how the backup sets in a multi-set are
arranged.

Layout of multi-volume, multi-node backup set

Within a multi-set, each backup set is split into two parts: the backup set and its
embedded table of contents. Just as a backup set TOC describes the contents of a
backup set, the MTOC describes the contents of the multi-set. It lists all of the volumes
used by the multi-set, and all of the individual backup sets contained within the multi-set.
In addition, it provides positioning information for each backup set, to allow one to
position either to the beginning of the backup set or to the beginning of its imbedded
TOC.
